Sahara Force India completed a busy day of practice at the Sepang International Circuit ahead of Sunday's Malaysian Grand Prix.

Paul Di Resta: "A very hot day in the car, but we got through most of the programme and have enough information going into tomorrow. There was an issue with one of the brake discs in the afternoon session, which probably looked more dramatic from outside the car, so the team made some changes before I started my long runs on the medium tyre. It's always difficult to read too much performance-wise from a Friday, but I would expect the midfield to be very competitive once again this weekend."

Nico Hulkenberg: "There's not a massive amount to say about today because it was a normal Friday where we focussed on getting on top of the tyres and trying to get the car in good shape for tomorrow. I think we learned quite a lot and the car feels totally different compared to Melbourne because of the track characteristics and the hotter conditions. The set-up work we did is promising for tomorrow and the long runs have given us lots of useful data, which was something we missed out on doing in Melbourne."

Jakob Andreasen, Chief Engineer: "As always on a Friday, the main priority was to try and get a good understanding of the tyres, which we managed to do with both the medium and hard compound. The driver feedback is encouraging and we demonstrated some good pace over the long runs this afternoon. Other items on the job list included the usual checks to our cooling solutions, especially the engine, as well as some aero comparisons this morning. The only small issue was the braking problem for Paul in the second session, which cost us some track time as we made changes to the brake material; but we understand what happened and will revert to a known solution for the rest of the weekend."
